What the K8AK-TS1 24VAC/DC Covers
The K8AK-TS1 24VAC/DC is a slim-line thermistor motor protection relay from Omron's K8AK-TS series, designed to monitor three-phase motor temperature, phase sequence, and phase loss in a single unit. It operates on a 24 VAC/VDC control supply and mounts on a DIN rail, making it a straightforward addition to a motor control centre panel without extra wiring for a separate phase monitor.
Phase and Output Ratings
The relay monitors all three phases of the motor supply — phase sequence and phase loss detection are built in, so a single device covers both the thermistor trip and the supply integrity check. The output is a single-pole double-throw (SPDT) relay rated 5 A at 250 VAC or 30 VDC, sufficient to switch a contactor coil or alarm circuit directly without an intermediate interposing relay.
